IMPROVEMENT IN BINDERS FQR SEWING-MACHINES.

Specification forming part of Letters Patent No. 112,019, dated February21, 1871.

To all whom it may concern:

Be it known that I, JACOB L. CoLEs, of the city of Newark, in the countyof Essex and State of New Jersey, have inventeda certain ImprovedAttachment to Binders for Sewing- Machines; and I do hereby declare thatthe following specification, taken in connection with the drawingfurnished and forming a part of the same, is a true, clear, and exactdescription thereof.

On the 3d day of January, 1871, Letters Patent of the United States No.110,740 were granted to me for certain improvements in binders adaptedto the purpose of laying braid upon the rims of hats.

My present improvement consists in combining with my binding-guide, asdescribedin said Letters Patent, an auxiliary U-shaped folder andsuitable edge-gages, and thereby provide a practicable means by whichsuch hat-brim stiffeners as are described in the Letters Patent issuedto J. W. Corey, November 1, 1870, may be neatly and evenly secured inposition by and beneath the braid, which is also simultaneously applied.

In the accompanying drawing, Figure 1 rep-' resents one of my improvedbinders complete in perspective. Fig. 2 represents the sameinlongitudinal vertical section. Fig. 3 represents, on an enlarged scale,a sectional view of my improved binding-guide, with the hatrim stiffenerand braid in position in the manner of its use.

It is considered unnecessary to enter into a detailed description of theseveral parts of the device not embraced within my present improvement,as they are not only Well understood by persons skilled in the art, butare described specifically in my Letters Patent referred to.

It is to be understood, however, that the Corey hat-brim stiffenerreferred to consists of a strip of textile fabric stitt'ened by theapplication of a solution of brittle gum. This stiffener is applied tothe rim of the hat folded, and extending from the top of the rim overthe edge and under the lower side. ()utside of this rim binding-braid isapplied in the usual m anncr.

A in the drawingre presents the main U- shaped guide. Between bed-plateb, bar 0, and block dis the space occupied by the bindingbraid, theadjustable books 0 and f serving as edge-gages.

B in the drawing represents an auxiliary U-shaped guide, which, in thiscombination, constitutes the important novel feature of my improvement.Between its exterior surfaces and the interior surfaces of the mainU-shaped guide A the Corey stiffener is introduced.

The adjustable barsjt andc' serve as ed ge-gages.

Between the inner surfaces of this auxiliary U-shaped guide B the rim ofthe hat is introduced.

In Fig. 3, 7c represents the hat-rim; m, the stiffener, .and 0 thebinding-braid.

The stiffener having a tendency to resist the laying action of thebinding-guides is liable to spring out of position after leaving theguide on its way to the needle. I have therefore devised and applied aspringpresser, C, which bears vertically. upon the top of the braid,immediately adjacent to the needle, and between it and the ends of thebinding-guides. By its action the two thicknesses of stiffener and braidare closely compressed between this presser and the bedplate, securing aproper relation between them during the stitching operation. This.spring-presser is capable of a great variety of constructions. I prefera simple spring-lever secured at one end of the bed-plate, as shown inthe drawing, on account of its simplicity and economy of manufacture, aswell as for its efficiency for the purposes desired.

Having thus described my improvements, I claim as new and desire tosecure by Letters Patent- 1. The auxiliary U-shaped folding-guide B,provided with edge-gages h and i, in combination with the main U-shapedfolding-guide A, over which the braid is folded, as and for the purposesspecified.

2. In combination with the auxiliary and main folding-guides A B, thespring-Presser C, as and for the purposes specified.

JACOB L. COLES.
